SBM Certification
Procedure
Page No. : 3 of 9
SECTION - 2 Philosophy & Purpose
EPCL believes that any individual responsible for emergency response should have adequate
knowledge about the hazards involved and his role statement. To standardize the level of
knowledge required for a SBM there should be minimum criteria all across EPCL.
2.2 Purpose
A SBM is required where there is a confined space hazard or high probability of electrocution .To
help protect a worker inside a confine space, many stake holders consider it a best practice to have
a stand by man the outside. OSHA advises these workers to always maintain contact through either
visual, or radio means. This monitoring allows the attendant to order the worker in the confined
space to evacuate and to contact emergency personnel to help with the rescue if necessary.
Note-1: According to OSHA about 90% deaths involving confined spaces occur every year.
Note-2: One study considered 40% of confine space fatalities involve attempted rescuers.

SECTION - 3 Confined Space?
Any work space that has a limited means of access or egress and is not intended for regular
human occupancy and has one or more of the following characteristics:
 Is large enough and so configured that an employee can enter and perform assigned work.
 Has limited or restricted means for entry or exit.
 Is not designed for continuous employee occupancy.
 No proper ventilation
 Contains or has the potential to contain a hazardous atmosphere.
 Contains a material that has the potential for engulfing an entrant.
 Has an internal configuration that might cause an entrant to be trapped or asphyxiated by
inwardly converging walls or by a floor that slopes downward and tapers to a smaller cross
section.
 Pits, dikes, ditches or excavations more than 04 feet deep or pits greater than 04 feet deep
that requires personnel to work with their heads below the rim.
 Contains any other recognized serious safety or health hazards for example;
O Process Vessels
o Boiler Feed Water Tanks
o Gas valve pit
o Waste Water pit
o GT’s Suction / Discharge plenum
o Internals of most Cooling Towers
o Effluent Treatment Tanks or Ponds
o Septic Tanks, Sewerage gutter
Entry requires special precautions, including a qualified and authorized Standby Person, and a
special authorization (Entry Permit)
3.1 Non permit Confined Space (non- permit space)
Means a confined space that does not contain any hazard itself or exposed to atmospheric
hazard which can cause death or serious physical harm. Provided safe means of entry / egress
from the confined space have been provided.
Unit Manager Operation, in consultation with HSE department, if required, shall decide
whether the confined space is non-work permit required or not.
Confined Space Entry permit can be exempted for excavated trenches of more than4 feet with
following arrangements:

1. Free from Slush & water.
2. Emergency exit route is free from tripping hazard (due to iron cage, demolished piles,
improper sloping etc.) and firm footing should be ensured at areas of entry / exit (access
and egress).
3. Proper means of entry / exit (ramps, runway or ladder) are available at every 75-ft or as
recommended by EPCL safety interface. These should be provided at least at two locations
in a pit.
4. Proper lighting arrangements should be provided at work area and points of entry /exit,
not less than 54-Lux.
3.2 Electrical Standby Person
On assessment of all risks involved in undertaking work associated with either lives (energized) or
De-energized equipment must consider all factors which may have the potential to cause injury or
damage, If this potential exists or any work in close proximity to live electrical equipment. EPCL
Electrical Engineer / Supervisor will depute a standby electrical person for precautionary measures.
3.3 Hazards of Confined Spaces
 Oxygen Deficient Atmospheres

SECTION - 4 Role of SBM
4.1 Confined space SBM role
 Know potential hazards; beware of the effect of hazards on entrants and how to control.
 Evaluate any changes of internal conditions as a result of work being performed within the
Confined space (smoke accumulation, oxygen deficiency during hot job inside).
 Know how to use entry & rescue equipment.
 Be familiar with the location of safety shower, exits, emergency siren, and the contingency
plan.
 Understand the rescue plan developed for that specific confined space
 Be physically capable of performing the duties assigned. The standby person is
responsible for stopping the job and ensuring personnel’s exit from the confined space if
emergency siren is sounded or any unsafe environment at the outside of confine space.
 Remain at the entry point as long as anyone is inside the confined space and remain alert
for anything that could affect the employee’s safety (e.g., fumes and noise). Keep
restricting entry of unauthorized persons. Perform rescue that does not require entry into
confined space
 Have a safety harness, plus a lifeline, a whistle (in case of work at heights or unavailability
of walkie-talkie / intercom/ whistle) and either a SCBA or fresh-air mask.
 Avoid the activities that interfere with primary role of attendant.
 Know / maintain a separate list of all those who are inside the confined space at all times
which must be placed on the entry/ exit point of the confined space.
 Frequently confirm that the personnel inside the confined space are all right. Alert and
inform them about any hazard. Ensure air hoses / exhaust pipes and life lines are intact
and remain in good shape. During an emergency situation (gas release /fire, sounding of
emergency siren), require them to exit the confined space and then discontinue use of
plant air.
 Assist in safe handling of materials and tools and in conveying messages.
 Use the walkie-talkie / intercom / whistle to call help in case of emergency. Communicate
with Control Room to sound the siren in case emergency warrants so. The standby person
must not enter the confined space, even in an emergency, until another qualified standby
person arrives and unless he has been trained as a rescuer.
 The standby person must not allow anyone to enter the confined space to start a rescue
unless he is part of the emergency squad / designated member of rescue team and is
wearing the necessary personal protective equipment. Also mention then name of rescue
